It clearly states NOT FOR SALE on the pass, yet they are a live auction on ebay? There are Fast Passes for sale on there too- not sure how that works though - I thought that FPs expired after the hours window that they can be used for?

We saw a guy trying to use some fatspasses to get on Haunted Mansion, as we walked past the cast member was telling him they couldn't accept the passes as the date had been tampered with. Never heard anymore.
